Control of Air Toxics
Three Programs:
- 1. Toxic New Source Review Program
- 2. AB 2588 “Hot Spots” Program
- 3. Air Toxics Control Measures and Rules
SLIDE 4
Toxics New Source Review Program
- Prevents significant increases in health risks
- Requires HRAs for new & modified sources of
toxic emissions
- Best Available Control Technology for Toxics for
significant new or modified sources
- Requires updated control for modified older, more
highly polluting equipment
Control of Air Toxics
SLIDE 5
Control of Air Toxics
AB 2588 “Hot Spots” Program
- Enacted 1987
- Facilities report toxic emissions to Air District
- Notify if risk exceeds threshold
- Reduce risk if risk exceeds risk action level
- Program is not sufficient
– HRAs up to 20 years old – Diesel PM was not included – Does not reflect new health risk information – Does not consider background risks – Is not flexible
SLIDE 6
Control of Air Toxics
Air Toxics Control Measures
- > 30 source-specific rules affecting toxic emissions
- National Emission Standards for Hazardous Air
Pollutants (NESHAPs)
- State Airborne Toxic Control Measures (ATCMs)
- Air District Developed Measures and Rules
SLIDE 7
Bay Area risk levels decline since 1990

SLIDE 8
Draft Rule 11-18
Reduce Health Risks to Lowest Achievable Levels
- Benefits impacted areas
- Incorporates latest health risk methodologies
- Promotes continuous improvement
- Ensures public transparency
- Provides greater flexibility
SLIDE 9
- Reduces facility risk action level from 100 in a
million to 10 in a million
- Incorporates new OEHHA Guidelines and health
values
- In the Bay Area facilities potentially affected include:
Draft Rule 11-18
- refineries
- gas stations
- hospitals
- foundries
- military facilities
- landfills
- crematoria
- sewage treatment
- chemical plants
- data centers
- schools / universities - power plants
SLIDE 10
- Air District staff will conduct health risk
assessments
- Facilities above 10 in a million must:
– Develop a risk reduction plan for Air District approval – Execute plan according to plan schedule
- Risk reduction measures include:
– Installation of Best Available Retrofit Control Technologies for Toxics (TBARCT) – Modification of operating hours and activity levels – Modification of emissions point characteristics
Draft Rule 11-18
SLIDE 11
Draft Rule 11-18
Implementation Approach
- Prioritize facilities
- Conduct Health Risk Assessment (HRA)
- Public Comment on HRA
- Publish HRA results to BAAQMD website & email
subscription list
- Risk Reduction Plan
– Publish requirement, submission and implementation status to BAAQMD website & email subscription list – 3-year implementation timeline – Could require faster implementation for CARE Communities
SLIDE 12
Implementation Phases
- Phase 1 (Prioritization Score > 250)
– Health Risk Assessments (2017-2018) – Risk Reduction Plan development and approval (2018-2019) – Risk Reduction Plan implementation (2019-2022)
- Phase 2 (Prioritization Score > 10)
– Multiple-source facilities (2019-2025)
- Phase 3
– Diesel internal combustion engines (2021-2027)
- Phase 4
– Retail gas stations (2023-2028)
Draft Rule 11-18
SLIDE 13
Next Steps
- Continue meetings and presentations to interested
groups
- Form Technical Working Group—Early 2017
- Public Hearings—May 2017
– Publish for review and comment March 2017 – Proposed rule language – Staff Report – Socioeconomic Analysis – CEQA Environmental Impact Report
SLIDE 14
- Long history of controlling toxic emissions
- Risk levels continue to decline – more work needed
- Rule 11-18 would:
– Reduce health risk to lowest levels feasible – Benefit impacted areas – Promote continuous improvement – Ensure public transparency – Provide greater flexibility – Phased Implementation – high risk facilities controlled first
